One thousand blank white cards. I used to have a short paragraph here that linked to a few other sites about the game. Unfortunately one of those sites no longer exists. Another one is now owned by a pornographer. This site is still around, anyway. Maybe I'll get around to writing up more about the game some day. (Don't hold your breath.) Anyway, you can also check out Wikipedia's article on the game.
Here are some of the first cards we made. You can view all the cards in my deck, split up by creator:
(I think I may have miscredited some of the cards. Mainly, I think I may have placed some of Fred's cards on Adam's page. But I'm not really positive, so I'm going to wait until Adam, Fred, or someone clears this up for me before I start moving around the images.)
